LP-294 REV. 2.20.14
DO NOT USE THIS APPLIANCE IF ANY PART HAS BEEN SUBMERGED IN WATER. Immediately call a qualified service technician.
The appliance MUST BE replaced if it has been submerged. Attempting to operate an appliance that has been submerged could create
numerous harmful conditions, such as a potential gas leakage causing a fire and/or explosion, or the release of mold, bacteria, or other
harmful particulates into the air. Operating a previously submerged appliance could result in property damage, severe personal injury,
or death.
NOTE: Appliance damage due to flood or submersion is considered an Act of God, and IS NOT covered under product warranty.
This boiler has wire function labels on all internal wiring. Observe the position of each wire before removing it. Wiring errors may cause
improper and dangerous operation. Verify proper operation after servicing.
If overheating occurs, or the gas supply fails to shut off, do not turn off electrical power to the circulating pump. This may aggravate the
problem and increase the likelihood of boiler damage. Instead, shut off the gas supply to the boiler at the gas service valve.
A. BOILER ERROR CODES
The display may show an error message and error code if any of the sensors detect an abnormal condition or an internal component
fails during the operation of the boiler, and the condition lasts longer than one second.
This message and code may be the result of a temporary condition, in which case the display will revert to its normal readout when the
condition is corrected
. This is known as a “Blocking” error, and will be indicated as such on the display with the letter “E”.
The code may also be the result of a condition that the controller has evaluated as not safe to restart the boiler. In this case, the boiler
control will be locked out, the red FAULT light will be lit, and the mes
sage “LOCKOUT” will be displayed on the display readout, along
with the letter “A”. In the case of a “LOCKOUT” error, the boiler will not start until a qualified technician has repaired the boiler and
pressed the RESET button for more than 1 second.
IMPORTANT NOTE: If you see error messages on your display readout, call a technician immediately, since the message may indicate
a more serious problem will occur soon.
B. USER INTERFACE DISPLAY
NOTE: If flame goes out after proper ignition and the boiler displays an error after too many flame failures, check the appliance type.

A01 IGNIT_ERROR 1
Five unsuccessful ignition attempts
in a row
Check ionization and spark electrode.
Check gas pressure. Check plugs at
gas valve and stepper motor.
A05 GV Relay Error 2 Failure detected in the GV Relay
Check gas valve plug and windings –
resistance. If correct, exchange BCU.
A05 GV Relay not open error 3 Failure detected in the GV Relay BCU must be exchanged.
A05 GV Relay not closing error 4 Failure detected in the GV Relay Check gas valve plug and windings –
resistance. If correct, exchange BCU. A06 Safety relay error 5 Failure detected in the Safety Relay
A06 Safety relay open error 6 Failure detected in the Safety Relay BCU must be exchanged.
A06 Safety relay closed error 7 Failure detected in the Safety Relay
Check gas valve plug and windings –
resistance. If correct, exchange BCU.
A00 Blocking too long error 11
Control had a blocking error for
more than 20 hours in a row. Reset the boiler and repair the blocking
error.*
